JPH05298521A - Detection mechanism for overs and shorts of package coin - Google Patents

Abstract

PURPOSE:To obtain a detection mechanism for overs and shorts of a package coin capable of eliminating the influence of a burr and wear, etc., by directly detecting the number of accumulated coins. CONSTITUTION:The piled number of coins can be counted essentially by counting the boundary line of the coin in the package coin M by a boundary line counter part 8. Thereby, a comparator part 10 can accurately judge the overs and shorts of the coin in the package coin M. In other words, the overs and shorts of the coins can be detected more accurately compared with a conventional overs and shorts detection mechanism in which the detection for overs and shorts of the accumulated coins is performed by detecting the height dimension of the package coin M indirectly and furthermore, including the dimensional error of the burr and the wear, etc., of the coin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for detecting excess or deficiency in packaged coins, which can reliably detect whether or not the number of accumulated coins is a predetermined number (50).

[0002]

2. Description of the Related Art Conventionally, as an excess / deficiency detecting mechanism in this type of packaged coin, one disclosed in Japanese Patent Laid-Open No. 3-612 is known. The device disclosed in this publication is a coin wrapping machine for sorting only coins of a designated denomination and vertically stacking them, then transferring the stacked coins to a wrapping unit and wrapping the stacked coins in a rod shape with wrapping paper. And an excess or deficiency detection mechanism for detecting whether the number of accumulated coins accumulated by the coin wrapping machine is excess or deficiency, and the excess or deficiency detection mechanism is provided so as to be vertically movable. , The upper and lower crimping claws for crimping the upper and lower ends of the wrapping paper wound around the accumulated coins, the rotary encoder for detecting the vertical movement amount of the upper and lower crimping claws, and the stacking based on the output of the rotary encoder And a detection unit that indirectly detects the height dimension of the coins and compares the detected height dimension with preset reference data to determine whether or not the number of accumulated coins is a predetermined number. Has been done.

[0003]

By the way, in the excess / deficiency detection mechanism configured as described above, the stacking height of the coins is indirectly detected based on the movement amount of the upper and lower crimping claws. However, there is a problem in that the number of accumulated coins cannot be accurately measured due to the susceptibility to dimensional error. That is, coins such as new coins have burrs, and circulating coins are worn. Therefore, the height dimension of the accumulated coins measured by the detecting means fluctuates depending on how much the new coins and the circulating coins are mixed in the accumulated coins. Therefore, the above-mentioned excess / deficiency detection mechanism updates the reference data itself, which is compared with the measured height dimension of the accumulated coins, to the latest average data to constantly respond to fluctuations in the height dimension of the accumulated coins. I had to. Further, the excess / deficiency detection mechanism configured as described above indirectly detects the height dimension of the integrated coins by the upper and lower crimping claws and the rotary encoder, and further includes dimensional errors such as burrs and abrasion. , The accuracy is low because it determines whether or not a predetermined number of coins have been accumulated.
There was a problem that it was erroneously determined that there was a predetermined number of coins, even though there were no predetermined number of accumulated coins.

The present invention has been made in view of the above circumstances, and detects the number of accumulated coins by counting the boundary lines of the coins, and thus the influence of burrs, abrasion, etc. is detected. It is an object of the present invention to provide a mechanism for detecting excess or deficiency of packaged coins that can perform the excluded detection.

[0005]

In order to achieve the above object, in the first aspect of the present invention, the excess or deficiency of packaging coins is detected to detect whether or not there are a predetermined number of coins in the packaging coins wrapped by the transparent packaging paper. A mechanism for irradiating the packaging coin with light in the longitudinal direction, and detecting the light amount of the reflected light reflected from the packaging coin along the length direction of the packaging coin, and the light amount of the reflected light. Based on the detection signal from the reflected light detection sensor and the reflected light detection sensor that outputs as a detection signal, the boundary line of the coin in the packaging coin is detected and counted, and the count value of this boundary line is output as detection data. A boundary line counting section,
The detection data output from the boundary line counter is compared with reference data stored in advance, and based on the comparison result,
A comparison unit for detecting excess or deficiency of coins in the packaged coins is provided.

In the second aspect of the invention, the boundary line counting unit is made to detect the boundary line of the coin from the waveform data obtained by integrating the detection signal from the reflected light detection sensor.

[0007]

In these inventions, the boundary line counting unit counts the boundary line of the coins in the packaged coin based on the detection signal from the reflected light detection sensor, thereby substantially counting the number of accumulated coins. Therefore, the comparison unit can accurately determine whether the coins in the packaged coins are excessive or insufficient. That is, the height dimension of the packaging coins is indirectly detected, and in comparison with the conventional excess / deficiency detection mechanism that detects excess or deficiency of the integrated coins by further including dimensional errors such as coin burr and wear. It becomes possible to accurately detect the excess or deficiency of coins.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a schematic configuration diagram of a coin wrapping machine, and in this figure, reference numeral 1 is three wrapping rollers rotatably provided around a vertical axis. These wrapping rollers 1 have a coin collecting and wrapping portion 2 formed at the center thereof.
Coins are fed inside one by one and accumulated vertically. The accumulated coins 4 accumulated in the coin accumulating and wrapping unit 2 are held by the three wrapping rollers 1 in a sandwiched state, and the wrapping rollers 1 and the accumulating coins 4 circle while rotating the wrapping rollers 1. By sandwiching the transparent wrapping paper 3 between the peripheral surface and the peripheral surface, the transparent wrapping paper 3 is wound around the accumulated coins 4. The wrapping roller 1 is at a position slightly separated from the accumulated coins 4 while the coins are accumulated in the coin accumulating and wrapping unit 2, but when the transparent wrapping paper 3 is wound, they are close to each other. The accumulated coins 4 are held between the packaging rollers 1.

On the other hand, in the vicinity of the packaging roller 1,
Upper and lower crimping claws (not shown) for crimping the upper and lower ends of the transparent packaging paper 3 wound around the stacking coins 4 are provided. The upper and lower crimping claws are provided so as to be close to and separated from the accumulated coins 4 accumulated in the coin accumulating and packaging unit 2, and the transparent wrapping paper 3 wound around the accumulating coins 4 when the coins are approached. The upper and lower ends of the transparent wrapping paper 3 are swaged by pressing the coin and rotating the stacking coin 4 by the wrapping roller 1 in this state. In addition, in FIG. 2, a rounded portion (a portion indicated by a solid line) near the upper and lower ends of the accumulated coin 4 is a crimped portion 3A of the transparent wrapping paper 3, and a portion extending vertically from the crimped portion 3A (two The portion indicated by the dotted line) is the end 3B before the transparent wrapping paper 3 is crimped.
Is. Therefore, in the end portion 3B of the transparent wrapping paper 3 wrapped around the circumferential surface of the coins 4, all the portions indicated by the chain double-dashed line are rolled inward by the crimping claws. In addition, in the following description, the accumulated coin 4 around which the transparent wrapping paper 3 is wound is referred to as a “wrapping coin M”.

Next, an excess / deficiency detection mechanism for detecting whether or not the coins in the packaged coin M are in excess or deficiency will be described with reference to FIGS. First, the reference numeral 5 shown in these drawings is a lamp arranged on the front side (the front side of the apparatus) of the coin stacking and packaging unit 2 into which the upper and lower crimping claws enter.
As shown in, the coin stacking unit 2 is provided in the vertical direction. Reference numeral 6 is a CCD that detects the reflected light when the packaging coin M is illuminated by the lamp 5 and outputs a detection signal corresponding to the brightness of the reflected light. As shown in FIG. It is provided in the up-down direction along the coin stacking and packaging unit 2 and is set to a range wider than the width of the transparent wrapping paper 3 before crimping (width before crimping).

The coin shown in FIG. 3 has a predetermined number of coins 4 accumulated in the coin accumulating and packaging unit 2 (50 coins in this embodiment).
A control device for detecting whether or not there is an amplifier, an amplifier 7, a boundary line counting unit 8, a reference value storage unit 9, and a comparing unit 1.
It is composed of 0 and. The amplifier 7 amplifies the detection signal output from the CCD 6 and supplies the amplified detection signal to the boundary line counting unit 8.

The boundary line counting unit 8 integrates the detection signal of the CCD 6 amplified by the amplifier 7, and based on the waveform data obtained as a result (shown by (a) and (b) in FIG. 4), the packaged coin M The boundary line of the coins inside is counted, and the counted value is supplied to the comparison unit 10 as detection data. Note that the transparent wrapping paper 3 wrapped around the accumulated coins 4 is printed with the denomination, the amount of money, the name of the financial institution, etc. Therefore, when the packaging coins M are detected, they are affected by these printed characters. However, since the CCD 6 directly detects the packaging coin M rotated by the packaging roller 1, the detection signals of the CCD 6 are averaged and are not affected by these printed characters.

The reference value storage unit 9 stores reference data to be compared with the detection data supplied from the boundary line counting unit 8. That is, when the packaging processing is normally performed, the number of coins of the packaged coin M is 50, so that the boundary line becomes 51 coins (including the upper and lower ends in the boundary line), whereby the reference value storage unit 9 stores. Stores the number of boundary lines (51) assuming the case where the packaging processing is normally performed as reference data.

The comparison unit 10 compares the detection data from the boundary line counting unit 8 with the reference data from the reference value storage unit 9,
If they match, a normal signal is output, and if they do not match, an abnormal signal is output. That is, in the comparison unit 10,
It is determined whether or not the detection data supplied from the boundary line counting unit 8 matches the reference data indicating the 51 lines supplied from the reference value storage unit 9, and the determination is made by the boundary line counting unit 8 based on this determination. A normal signal is output as normal when the detected data indicates 51, and an abnormal signal is output as abnormal when the detected data has a numerical value other than 51.
Then, the normal signal and the abnormal signal output from the comparison unit 10 are supplied to an output unit (not shown), and the output unit informs the worker that an abnormality has occurred in packaging the coin, based on the abnormal signal. I am trying to do it.

Next, the processing contents of the detection signal in the boundary line counting section 8 will be described with reference to FIG. The boundary line counting unit 8 integrates the detection signal of the CCD 6 amplified by the amplifier 7 and, as a result, obtains the waveform data shown in FIGS. The waveform data of (a) is before the transparent wrapping paper 3 is crimped by the upper and lower crimping claws, and the waveform data of (b) is the transparent wrapping paper 3 is crimped by the upper and lower crimping claws. It is the latter one. Then, in the waveform data (a) before crimping the transparent wrapping paper 3, the reflected light is reflected from the end portion of the transparent wrapping paper 3 (the portion indicated by the chain double-dashed line 3B in FIG. 2) as indicated by the reference numeral (c). Therefore, both ends of the waveform are H, while in the waveform data (b) after the transparent wrapping paper 3 is crimped, the ends of the transparent wrapping paper 3 are bent (see FIG. 2). 3A), the reflected light from the transparent wrapping paper 3 is not obtained, and therefore both ends of the waveform are L as shown by the reference numeral (D).

Although the transparent wrapping paper 3 is made of a transparent plastic sheet, the transparent wrapping paper 3 is not in close contact with the cylindrical surface of the accumulated coins 4, that is,
In the portion 3B indicated by the chain double-dashed line in FIG. 2, irregular reflection of light occurs on the surface thereof, and the level becomes H as indicated by (c) in the waveform data (a). On the other hand, when the transparent wrapping paper 3 is in close contact with the cylindrical surface of the coins 4, the light does not reflect on the surface, and the light passes through the transparent wrapping paper 3 as indicated by symbols (A) and (B). Then, the light is reflected by the cylindrical surface of the integrated coin 4 which is in close contact with the transparent wrapping paper 3.

Waveform data (a) and (b) in FIG.
The range shown in (B) will be described. These (A)
The range shown in (B) shows the waveform data of the portion where the integrated coins 4 are wrapped by the transparent wrapping paper 3, and the place where “H” is shown in these (A) and (B) is , Shows that the light of the lamp 5 is transmitted through the transparent wrapping paper 3 and reflected by the cylindrical surface of the integrated coin 4. On the other hand, in the place of “L”, the light of the lamp 5 is transmitted through the transparent wrapping paper 3. It shows that the coins 4 have been absorbed between the coins (that is, the boundary line). It should be noted that light is also absorbed at the upper and lower ends of the coins located at the upper and lower ends of the accumulated coin 4, whereby "L" as indicated by the reference signs (a) and (b).
It becomes the level of. In the boundary line counting unit 8, the waveform data (a), (b), (a) and (b) are also included in the boundary line of the coin.

Then, in the boundary line counting unit 8, "L" in the range shown by (A) and (B) in the waveform data (a) and (b) is represented by the number representing the boundary line between the coins of the accumulated coins 4. As the detection data, and the comparison unit 1
It is output to 0, and the comparison unit 10 determines whether or not the number of the accumulated coins 4 is normal based on the detection data.

As described above in detail, in the excess and deficiency detection mechanism for packaged coins shown in the present embodiment, the boundary line counting unit 8 counts the boundary lines of the coins in the packaged coins M, so that the coins are substantially coined. It is possible to count the number of accumulated coins, and thereby the comparing unit 10 can accurately determine whether the coins in the packaged coins M are excessive or insufficient. That is, as compared with the conventional excess / deficiency detection mechanism that indirectly detects the height dimension of the packaging coin M and further detects the excess / deficiency of the accumulated coins by including dimension errors such as burrs and wear of the coin. The effect that the excess / shortage of coins can be accurately detected is obtained.

The waveform data (a) shown in FIG.
As shown in (b), the pulsed "L" signal is obtained before the transparent wrapping paper 3 is crimped by the upper and lower crimping claws and after the transparent wrapping paper 3 is crimped by the upper and lower crimping claws. Since it is effectively detected, the timing of detecting the reflected light by the CCD 6 and the timing of counting the boundary line by the boundary line counting unit 8 are the same as before the crimping of the transparent wrapping paper 3 and that of the transparent wrapping paper 3.
It may be set to any value after tightening. Further, in the present embodiment, the number of coins accumulated is set to 50,
The number of sheets can be arbitrarily set by changing the setting of the reference data in the reference value storage unit 9.
Furthermore, in this embodiment, an excess / deficiency detection mechanism of the packaging coin M is
The case where the coin is packed in the coin wrapping machine between the wrapping rollers 1 has been described, but the present invention is not limited to this. For example, coins stacked by an independent stacking mechanism may be inserted between the wrapping rollers. It may be incorporated into a coin wrapping machine that sends in and winds and wraps the transparent wrapping paper.
